摘要
论文对随机共振技术运用于强噪声背景下的弱信号检测进行了研究。针对工程测量的实际要求,提出了一种随机共振的自适应算法,并开发了一套面向工程实用的自适应随机共振系统。运用于开关电源的故障信号检测,取得了较好结果。
The technology of stochastic resonance can be used to detect weak signals submerged in noise. According to the requirement of engineering signal detection, an adaptive stochastic resonance algorithm is proposed. Associated engineering-oriented adaptive stochastic resonance system is also developed. Such developed diagnoses system has been successfully applied to detect the fault signal of power supply apparatus.
